Abstract
A method for providing safety protection in an additive manufacturing apparatus for forming a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article is provided. The method comprising the steps of providing a position detecting device connected to a control unit to detect whether a foreign matter is within the enclosable chamber. The method may also include, upon detecting that the foreign matter is within the enclosable chamber, either (1) switching off, via the control unit, at least one device associated with the additive manufacturing apparatus; or (2) providing power to a powder suction device. Associated safety protection devices are also provided.

A method for providing safety protection during formation of a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article, said method comprising the steps of:
- providing a position detecting device connected to a control unit of an additive manufacturing apparatus configured for forming said three-dimensional article, said position detecting device being configured to detect a position location of a foreign matter within said enclosable chamber;
- and
- upon detecting said position location of said foreign matter within said enclosable chamber, switching off, via said control unit, at least one device associated with said additive manufacturing apparatus.
A method for providing safety protection during formation of a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article, said method comprising the steps of:
- providing a position detecting device connected to a control unit of an additive manufacturing apparatus configured for forming said three-dimensional article, said position detecting device being configured to detect a position location of a foreign matter within said enclosable chamber;
- and
- upon detecting said position location of said foreign matter within said enclosable chamber, providing power to a powder suction device.
A safety protection device for forming a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article, said safety device comprising:
- a position detecting device connected to a control unit of an additive manufacturing apparatus configured for forming said three-dimensional article, said position detecting device being configured to detect a position location of a foreign matter within said enclosable chamber;
- and
- a switch for switching off at least one device associated with said additive manufacturing apparatus, said switch being controlled by said control unit and being activated when said position detecting device detects said position location of said foreign matter within said enclosable chamber.
A safety protection device for forming a three-dimensional article through successive fusion of parts of a powder bed in an enclosable chamber, which parts corresponds to successive cross sections of the three-dimensional article, said safety device comprising:
- a control unit of an additive manufacturing apparatus configured for forming said three-dimensional article, said position detecting device being configured to detect a position location of a foreign matter within said enclosable chamber;
- and
- a powder suction device configured such that said control unit only provides power to said powder suction device when said position detecting device detects said position location of said foreign matter within said enclosable chamber.
